------- Comment #18 from jv244 at cam dot ac dot uk 2009-05-17 05:11 -------
the patch posted here:
http://gcc.gnu.org/ml/fortran/2009-05/msg00244.html
allows cp2k in its single source file form, 640klines as made available in
PR40005, to compile with -fwhole-file (using the ulimit -s unlimited trick).
Even the 3Gb memory usage seems reasonable. What about turning this option on
by default now ? The warnings its generates are generally useful, and there is
the potential gain in performance.
